would someone please be able to help me out with some vega 64 timings and clocks and maybe ppt tables to get power usage below 200W at wall? been getting 48mh @200w from wall from each card, i imagine i can do better.

Settings in pic run ~168w/GPU including idle ATW (120v, 1600 plat PSU).  amdmemtweak params are --RAS 30 --RCDRD 14 --RCDWR 6 --RC 44 --RP 12 --REF 11700 --RRDL 4



Thanks mate ill give them a run. im on windows though and dont think i can get voltages down that low without powerplay tables? think its capped at 900mv.

You can use ODNT to easily create a PPT similar to my clocks/voltages listed on the right.  Only difference is that you may need to use mem P2 set to 1028 (and lock out P3), in order to take advantage of the power savings of a reduced SOC clock.

Btw, if you really want to get crazy, there's been a lot of noise about flashing a 64 w/ a 56 BIOS (yes, the reverse of what most people have been doing) to get higher hashrates at lower power.  Not sure which models this actually works for tho, and haven't tried it myself... yet.
